kernel: Linux kernel: Use-After-Free vulnerability in ATM subsystem

A flaw was found in the Linux kernel's Asynchronous Transfer Mode ATM subsystem. An authenticated local attacker could exploit a Use-After-Free UAF vulnerability in the /proc/net/atm/lec handling. This flaw occurs due to improper devput calls without prior devhold calls, leading to an imbalance i...
